基于matlab的ofdm仿真，效果很好(Based on the ofdm matlab simulation, good results)

模糊c均值聚类的一种改进算法，比较简单。用的时候先初始化一下，在不断迭代，参考里面的main函数吧。参考的时候去掉一些无关的命令，有些命令是我自己调用的无关的命令，可能目录里面没有，但不妨碍这个算法运行，可以屏蔽掉。(an improved fuzzy c means clustering algorithm)

说明：  bpsk 调制，awgn信道，ldpc 系统编码，概率域解码 (BPSK modulation, awgn channel, ldpc system coding, the probability of domain decoding)

matlab学习资料 简明实例教程 主要介绍了编程的注意事项(matlab learning materials condensed example tutorial introduces the programming Note)

该函数为OMP算法的函数实现，可以直接来调用，其根据沙维老师的CS_OMP改编(This function is a function of OMP algorithm to achieve, you can call directly to their teacher s CS_OMP adapted according to Shawei)

谱分析的源程序，适合通信等专业的初学者学习使用，希望给需要的人帮助(Spectral analysis of the source, suitable for beginners to learn communication and other professional use, I hope to those who need help)

实现能量检测仿真，由main函数进行能量检测，psk_2实现BPSK调制，pdsnr计算出理论值，最后由main给出理论与仿真之间的画图比较。(Achieve energy detection simulation, the main function of the energy detection, psk_2 achieve modulation BPSK, pdsnr calculate the theoretical value, and finally given by the main draw between theory and simulation comparison.)

说明：  计算给定矩阵的互信息，这时的相关性是利用互信息来判断，矩阵的形式为邻接矩阵(compute the mutual information of the given matrix such as the matrix the elements in it are 0 or 1.)

compiler available M16 absolutely the HD7279 drive test procedures [pml2dtm.zip] - photonic crystals can be calculated with the procedures used Matlab to prepare, easier to understand!

This MATLAB M-file will produce the FDTD solution of a z-directed line source in a two-dimensional TMz computational domain excited
